Question about colors and batch scan

Postby Hawk » Fri Aug 05, 2011 2:31 pm

Hi.

I've recently bought SilverFast SE Plus for my old Minolta Scan Dual III. It works fine, but there are two issues I'd love to get resolved.

1. Colors of (pre)scanned image are bad. While I have no problems fixing them with levels, curves and other SF tools I'm wondering why they look perfectly fine on frames overview (index with all frames)? Is there any way to have colors/exposure of prescan/scan identical to thumbnails in index? That would save me lot of time as index most often have near perfect colors/exposure :-) Using SF auto correction and NegaFix usually don't get even close to colors seen on thumbnail without manual adjustments.

2. I'm also having problems with exposure and colors in batch scan. It seems that settings from first frame are used for all other frames. For example if first frame is very dark it will be scanned fine (exposure bumped), but all other will be overexposed. If first frame have dominate color (ie. blue sky, lots of green leafs etc.) all other frames will have cast of that specific color. I can get around it by prescanning one frame. Doing batch scan right after that seems to force prescan auto correction to all batch scanned frames. I can live with that when scanning similar frames, but its quite annoying when batch scanning negatives with different kind of frames (dark/light, interiors/landscapes etc.). I usually give up doing batch scan in such situations as scanning each frame separately gives me way better results.

Dear customer,

The color adjustments depend on the image content inside the scanframe.
Make sure no unexposed film material is inside the scanframe.
You can change the scanframe without changing the content if you deactivate the NegaFix check-mark for auto.


For batch scanning make sure you activate the "Auto for batch" option in the options auto tab.
This will execute the image auto adjust for every image.
Also check that each image uses the correct setting.
Each frame has individual settings.


kind regards,
Arne Ketelhohn

As for colors I was only wondering why index (overview with all frames) have near perfect colors and if its possible to keep that color settings/correction on prescan and final scan. Auto correction executed on prescan usually isn't even close to these colors.

And batch scanning... where I can find this "auto for batch" option in SE Plus? I don't have "Auto" tab in options. Only "General", "CMS" and "Special"

Still awaiting answer :-) Will be thankfull for any hints. Is "Auto for batch" available in SE Plus or do I have to live with corrections settings of first frame being applied to all frames?

The option might also be called "Automatic with ADF" depending on the device used.

I'm using SilverFast SE Plus for Minolta Scan Dual III... Still no luck. There is no "Auto" tab in options and I can't find "Auto for batch" nor "Automatic with ADF" anywhere in options or any other settings.

You are right, that option is only available in SilverFast Ai (Studio).
I got that mixed up, sorry.

Any chances then to have batch scan in SE Plus use separate correction settings for each frame? Some file/registry edit trick perhaps? Its rather crucial option for batch scans. If its not possible with currect SE Plus 6.x, are there any chances for little 6.x series update adding that option in SE Plus?

No there are no changes in the SF 6 feature availability planned.
The only way would be to upgrade to Ai.
